PULLEIY.

Application filed March 23 To all whom it may concern Be it known that I, WARREN IVESLEY YALE, a citizen of the United States, residing at Chickashzuin the county of Grady and State of Oklahoma, have invented certain new and useful Improvements in Pulleys, of which the following is a specification. 4

This invention relates to new and useful improvements in pulleys, and more particularly to a pulley designed to feed a substance to a belt whereby to'prevent said belt from slipping on the pulley.

The primary object of the invention is to provide a device of this character in which the rim or fe-lly is designed hollow within which the anti-slipping substance is supwhereby this substance is automatically fed to the belt extending thereover.

Another object of the invention resides in providing a pulley in the hollow felly on which are formed plurality of openings in which are inserted porous plugs which feed transfer the same to the belt.

Still another object resides in providing a pulley which is simple and durable in construction, inexpensive to manufacture and one which willbe very efficient and useful in operation. V

IVith these and other objects in view my invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claims.

In the accompanying drawing- Figure l is a side elevation of a pulley constructed in accordance with my invention with parts broken away;

Fig. 2 is a front elevation of the same;

Fig. 3 is a longitudinal section therethrough as seen on the line 3-3 of Fig. 1.

In describing the invention I shall refer to the drawing in which similar reference characters designate corresponding parts throughout the several views, and in which 1 designates the hub of my improved pulley from which radiate a plurality of spokes 2, and 3 designates the felly thereof. This pulley is preferably cast in two sections and the telly designed hollow. The two sections of the pulley are held together by means of bolts 5 which extend through the hollow 1921..

results accomplished by the essential fea- The outer peripheral rim of the fell y provided at regular intervals with openings- 6 in which are inserted plugs '7 formed of soft wood, fiber, or, other porous material.

These plugs may be termed oil feeders for the purposes hereinafter described, Z

In operatlon, the hollow'felly 3,1nay be filled with a substance adapted tov preventa' belt' from slipping and as the pulley" isrotated, this substancethrough capillary action and centrifugal force is adapted to be absorbed by the feeders 7 and passed to the over the pulley. Thus, the belt-is supplied with this substance automatically, and slipping of the belt on the pulley is prevented.

There are various kindsof anti-slipping substances which may be used incarrying out my invention, as for 'examplefish oil; I do not wish to limit myself to any particular kind .of substance to be used, except that it be a substance of a certain adhesive or anti-slipping quality. It may be further desirable under certain circumstances to' eliminate the feeders 7 and utilize an anti slipping substance in powderedor paste directly to the belt throughout the openings N form suchfas graphite, which may be fed 6 in the pulley.

inner face of the belt asthesamfe operates 1 From the foregoing'it will be seen tha-tflI I have provided a simple, inexpensive and efficient means for carrying out'the objects of" the invention, and while I have particularly described the elements best adapted to perform the functions set forth, it is obvious I I that various changes in form, proportioi'i, and inth'e minor details'of construction may be resorted to-without departing from the spirit'or sacrificing any ofthe, principles of the invention. I i

Having thus described my invention, what I claim is:

1. A pulley wheel provided'with a pe ripheral chamber adapted to containan antislipping substance, and means for feeding said pulley Wheel.

2. A pulley wheel provided with a peed to contain an anti-slipping liquid,' the ripheral chamberadapted to contain an antiouter Wall of said chamber having openings 10 slipping substance, and feeders associated therein, and porous feeders fitting Within With said chamber for supplying said subsaid openings for supplying said liquid to a 5 stance to a belt adapted to pass" over said belt adapted to pass over said Wheel;

pulley Wheel. I In testimony whereof I afiix my signature.

3. A pulley Wheel having its periphery provided with a peripheral chamber adapt WARREN WESLEY YALE.
